极微细的排气孔,能将模具内的瓦斯或空气立即排出子模具外,简单而最有效果的産品爲提升塑胶成型生産性能发挥威力.
有效解决下列之间题:
烧焦
树脂的填充较排气快时, 空气受断热压缩,前端部变成高温,依情形而定, 会引起变色,烧焦等问题。
溢料
在结合部前端的树脂温度上升,粘度下降,而易发生溢料,另外,空气造成填充障碍,则射出压力上升,结果模具微张,而全体发生溢料。
填充不足
虽然没有烧焦、溢料发生,但因空气造成的阻力,减缓了填充比率,造成填充不足的现象。
气泡银线
空气与树脂凝缩造成气泡、银线、污点等外观不良问题。
循环时间延长
若提高树脂温度,模具温度,降低射出速度,虽然这些不良现象不会发生,但使循环时问延长。
节省能源、节省时间、节省成本
若从设计阶段开始考虑TX排气栓的话, 模具的试模次数、时问、材料均可减少。
装入排气栓的费用与时间约以往的1/3-1/10。
排气栓使用方法:
1.排气栓在压入模具时,表面请勿直接打击.
2.排气栓在压入模具时,请使用JIS规格H7/S6之公差。
In order to achieve its maximum molding productivities simply using its ultra micro breathing cell to
exhale gas and air from molds .
Common Questions
1.Burnt
When aberration and burnt issues occurred,it is because resin is filling faster than air exhaling
which will result gasvent to overheat.
2.0verflow:
There are 2 possible conditions:
When temperature of resin gets higher at the tip of seaming ,it weakens its bonding strength
Air can filled up the path and blocks resin to flow functionally which will cause ejection pressure
to rise and materials to overflow.
3.Not enough fillings:
Due to air pressure ,it reduces the ratio of the filling speed. Even there is no any sign of burnt or overflow.
4.Cell Streak:
If there are some cells,streaks and mottles occurred ,it is because the cells have not been
vaporized completely between air and resin.
5.Extensive Cycling Time:
The higher temperature of resin , molds and slower speed of injection cause extensive cycling time ,
however ,it will not affect the quality of final products.
Energy,Time,and Cost Saver
1.It will reduce the trial die ,time and materials if users consider to use TX gasvent the beginning of the design.
2.It will save up to 1/3 to 1/10 of the total cost and time if installing gasvent.
Installation:
1.Do not touch the surface when gasvent is in use.
2.Use H7/S6 from JIS reference chart.
